LISTINGS FOR COLUMN "ASTRONOMY FROM Å to ZZ"
(A column that ran in the Alachua Astronomy Club's Newsletter, FirstLight)
Dictionary of Terms
(Click for PDF Index)
Astronomy is rich with terminology. Common dictionaries contain many of these terms because the English language includes many astronomical words in popular speech. (For example, elongation, gibbous, menses, star and synodic are all in unabridged English dictionaries.) This column briefly introduced a new but basic astronomical term (word, acronym or abbreviation). Began January 1999 with the letter a, each column was alphabetical using successive letters for each article's entry.
(Column ran monthly from 1999 through 2001, then only a few times from 2002 to 2008)
